Device

Connected

On There is a valid connection to a device.

Off There is no device connected to the port.

Power Status

(green and

orange)

On The unit is supplying power to a connected device.

Off One of these conditions exists:

• There is no connected device.

• A connected RPS device does not require power.

• A connected EPS device has not successfully communicated for EPS power.

Blinking

orange

One of these conditions exists:

• On the HP 630 RPS/EPS, RPS power is not available to the connected device

because there is a hardware or power supply failure in the HP 630 RPS/EPS unit.

• When the LED is blinking simultaneously with the Fault LED, there is a fault

condition on the port. If the Fault LED is not blinking there could be an overcur-

rent condition from the connected switch.

The blinking behavior is an on/off cycle once every 0.8 seconds, approximately.

The blinking behavior is an on/off cycle once every 1.6 seconds, approximately.

Specific fault conditions can be viewed by checking switch log files.
